1) Punching. Limited range, safer, basic.
2) Kicking. Feet. Some can leave you off balance or exposed, but you get better range.
3) Throwing. Ranging from tripping people up to hurling them around. Need close contact.
4) Restraining. Either standing or lying down, controlling an enemy by restricting their movement, may or may not include joint locks.

You could also mix up weapon attacks and kicks and punches, maybe using the mentioned guideline on "second guesses" (for example, I swing my sword sidewise and, if he parries me, I throw a kick...)

That Sounds Painful!

He just sits there tapping away all day on a tiny screen. But he tells everyone that he is slaying Orcs.

If you look at pure damage charts, a pistol may not look like an exceedingly interesting option, but if you think that it makes sense that a pistol, when it hits, leaves a bullet inside your opponent, well... there should be something more than just a straightforward damage, there...
